to-zst(1) General Commands Manual to-zst(1)
NAME
to-lzma - converts .Z, .lzo, .zip, .rar, .gz, .bz2, and .bz3 files to
zstd format
SYNOPSIS
to-zst [-(IPv)4] [-(IPv)6] [-d(elete_original)] [-h(elp)]
[-k(eep_smallest)] [-m(ax_compress)] [-n(o_overwrite)] [-p num_cores]
[-t(imestamp_retain)] file/URL...
DESCRIPTION
to-zst recompresses files compressed with the compress, lzop, zip,
gzip, bzip2, and/or bzip3 utilities into zst format. The newly
compressed files will usually have a .zst extension. If a specified
file is actually a URL, it will be downloaded using wget and then
recompressed.
OPTIONS
-4 Prefer IPv4 when downloading a URL.
-6 -6 Prefer IPv6 when downloading a URL.
-d After each file is compressed, delete the original.
-h Print help and quit.
-k Once a file is successfully recompressed, delete the larger of
the original file or the new one. This option maximizes disk
space savings and is incompatible with the -d option.
-m Compress more, but at the expense of increased CPU time and
memory usage.
-n Do not overwrite the target .zst file if it already exists.
-p num_cores
Use the multi-threaded -T option of zst to utilize multiple
cores during compression. Note that the output file, while
being fully compatible with unthreaded zst, will generally be
slightly larger. Specifying a num_cores value of zero will
utilize all available cores.
-t Make the timestamp of new files match those of the old files.
